What are the motifs in Woman at Point Zero by Nawal El-Saadawi?

Eyes play a recurring role in Woman at Point Zero. In the Author's Preface, Nawal El Saadawi notes the stern look of Firdaus' brown eyes and claims that Firdaus is distinguished from other women by the way she looked at Saadawi from the depths of her eyes. It is as though Saadawi dies the moment that her eyes make contact with Firdaus' eyes, which are unwavering eyes that kill by cutting deep down inside like a knife.
